use esp32 as the mcu for 3D printer motherboard.with esp32 you can control and upload files to your printer easily and there are a lot of open souce and application for esp32,for example play music at boot ... you can also use it as laser CNC control board with Grbl_ESP32.
the biggest problem is there are not enough GPIOs for esp32 as the mcu of the 3D printer motherboard. here I add one fast expander chip,let it can support 8 driver motors,and all kinds of LCD.
